Merge commit '4a1418e07bdcfaa3177739e04707ecaec75d89e1' into upstream-merge

* commit '4a1418e07bdcfaa3177739e04707ecaec75d89e1':
  Unbreak large mem support by removing kqemu
  Add a configure switch to enable / disable all user targets. I felt compelled to do it for symmetry, mostly it is useful to disable user targets when you don't want to build them.
  Migration via unix sockets.
